I don't get your question. You meant you could not make a call or your contacts wasn't reachable. Did you see Koodo service in your phone? If you could not get your contact, it could be their network issues, not yours.
I try to phone J. I phone her every day with my cell from my home. printing comes up on my phone saying" out of service area" Ditto for all of my friends. Plus when i call my cell with the landline it goes immediately to my VM.
